Beyond worried please help
OK so I am currently 13w2d pregnant with my second child. I had a miscarriage in Dec 09. So up until about a week ago I had a hard knot above my pelvic bone so I was think everything was OK with the baby. But now the knot is not there I have had some cramping but they feel like menstural cramps nothing major like my first miscarriage and no bleeding. But what has brought me to think that my baby is no longer alive because I sat in the hot tub too long and I think I may have killed it not on purpose. I feel no emotional attachment to this baby anymore like I am not pregnant anymore. I do not have an appt until Aug 27 and I am scared to go because if they can't find the heartbeat I will know that this was my fault and I accidentally killed my baby. Should I be worried? I am not sure if this feeling is because I am not so emotional anymore since I have entered my second trimester or what is going on. SOMEONE PLEASE HELP ME
